Abstract

An apparatus and method for placement of a tubular body in the urethra. The tubular body includes a proximal portion adapted for placement toward a bladder end and bladder neck end of the urethra and a distal portion opposite from the proximal portion. A sensor component located on the tubular body is responsive to a feature of the urethra and outputs a first signal indicating proper placement of the proximal portion of the tubular body relative to the bladder and bladder neck. Preferably, an insertion tool is used during positioning of the urethral apparatus. The insertion tool is coupled to the distal end of the urethral apparatus and is used to push the urethral apparatus proximally in the urethra. The first signal can be transmitted from the urethral apparatus through the insertion tool from which it is perceivable by the person positioning the urethral device. Upon proper placement, the insertion tool is decoupled from the urethral apparatus and withdrawn leaving the urethral apparatus in place in the urethra with the proximal portion properly positioned relative to the bladder neck and bladder.

Claims

1. A method of positioning a tubular body of a urethral apparatus having a sensor located on the urethral apparatus in a urethra comprising the steps of:

inserting a proximal end of the tubular body of the urethral apparatus having a sensor located on the urethral apparatus in the urethra;

manually moving the urethral apparatus proximally toward the bladder;

receiving an indication from the sensor located on the urethral apparatus that the proximal end of the urethral apparatus is at the bladder; and

ceasing movement upon receiving the indication from the urethral apparatus that the proximal end is at the bladder.

2. The method of claim 1 wherein said indication causes an audible signal to sound.

3. The method of claim 1 wherein said indication causes a visually observable signal.

4. The method of claim 1 further comprising the step of:

coupling a distal end of the tubular body of the urethral apparatus having a sensor to a proximal end of an insertion tool prior to the step of manually moving the urethral apparatus proximally toward the bladder.

5. The method of claim 4 further comprising the step of:

decoupling the insertion tool from the urethral apparatus having a sensor after the step of ceasing movement thereby leaving the urethral apparatus in place in the urethra.

6. The method of claim 4 wherein said indication is transmitted through the insertion tool.

7. The method of claim 5 comprising the steps of:

after the step of decoupling, removing, removing the insertion tool from the urethra; and

after a period of time, removing the urethral apparatus by advancing the proximal end of the insertion tool into the urethra, coupling the distal end of the tubular body of the urethral apparatus with the proximal end of the insertion tool, and withdrawing the coupled insertion tool and urethral apparatus from the urethra.

8. The method of claim 4 further comprising the step of:

after the step of coupling the insertion tool to the tubular body, receiving a signal from the insertion tool that the insertion tool and urethral apparatus are coupled together.

9. A method of positioning a urethral apparatus having a sensing component located on the urethral apparatus comprising:

coupling a distal end of the urethral apparatus having a sensing component located on the urethral apparatus to a proximal end of an insertion tool;

advancing the coupled urethral apparatus and insertion tool proximally through the urethra toward the bladder;

sensing a change in a feature of the urethra with the sensing component located on the urethral apparatus;

transmitting a signal in response to said sensed change from the urethral apparatus to said insertion tool; and

providing a signal from the insertion tool that the proximal end of the urethral apparatus is properly positioned relative to the bladder neck and bladder.
